LUEIRIGA'IING DEVICE.

- To all whom it may concern:

Be it known that I, Lnwrs S. WATREs, a citizen of the United States, residing at Scranton, county of Lackawa'nna, State of Pennsylvania, have invented certain new and useful Improvements in Lubricating Devices, of which the following is aspeciiication.

This :invention comprises a forced feed lubricatorin which the motive power for of fluid under pressure without connection with any moving part of the engine or aparatus to which it is applied. To this end,

drive the lubricant leed devices, through pawland ratchet devices, by power obtained frbm an expansible diaphragm operated intermittently by pressure of an engindex haust, or by pressure of the fluid constituting the motive power of an engine, or by pressure of a fluid handled by the a paratus to be lubricated. The pressure si e of the diaphragm may be in connection with the end of the cylinder of a steam engine, gas engine, or of a pressure or liquid force pump.

The accompanying drawing shows the in vention embodied in a practical and ellicient form.

Figure 1 is an elevation partly in section: and Fig. a section through the expansible diaphragm and some associated. parts.

a indicates an oil receptacle, and b an oil pump plunger coupled by a connecting rod with a crank on theshaft of a ratchet wheel 0. In the bottom of the oil tank is a downwardly opening spring so )ported valve (1 which, when unseated by the suction of the pump plunger, permits passage of oil to the chamber e belpw the pl nger. An aperture inthe bottom of this chamber is closed by an upwardly spring-pressed valvef which is unseated on the downward stroke of the plunger and permits oil to pass by the passa e 9 to the part of the apparatus to be The ratchet wheel is driven by I a push pawl rod h pivoted at h. to a valve stem that passes througl'ian expansible Specification of Letters Patent.

diaphragm confined at its edges in'a circular frame j forming a pressure chamber on the under side of the diaphragm. The passage way 7c to this chamber is formed with a valve seat m and on the stem i is a downwardly opening valve m adapted to close against said seat when the diaphragm is lifted by pressure of fluid entering through 70.

stem i where it passes through the diaphragm s screw threaded as shownat z and ass applied to it an adjusting nut by means oii' which the valve *m may be regulated with reference to its seat so as to shut oil'the fluid pressure after a determined extent of ex- 'pansion of the diaphragm has occurred. A spring 0 of any appropriate character, a coiled spring being shown, is applied to the pawl rod h and serves to maintain it in contact with the periphery of the ratchet wheel. On each accession of pressure of fluid in the passage 7c, the diaphragm is raised causing the pawl h to drive the ratchet wheel through one step or increment of movement. Sue cessivesteps of movement of the ratchet wheel alternately will produce reciprocation of the oil pump plunger.

In order to regulate the distance through which the ratchet wheel will be rotated on each actuation 01" the pawl rod h, that rod is made adjustable to any length so that it may be caused to engage the ratchet wheel at different points. ily be accomplished by making the pawl rod h in two parts telescoping ina coupling sleeve p and held in desired position therein by cross pins or bolts 7%.

I claim my invention:

1. Forced feed lubricating devices for engines and like a paratus comprisim the coinbination of a qubricant receptacle, an oil pump, appro )riate valves, a ratchet wheel by which the oil pump is operated, a pawl rod engaging the ratchet wheel. to ell'ect its step by step rotation, an expansiblc diaphragm mounted upon a stationary part of the apparatus and connected with a chamber adapted to be subjected to variable fluid pressure and mcans operated by the expansi'on of the diaohragm to shut oil the iiuid pressure from the dia hragin when a desired degree of expansion or the latter has been obtained.

2. Forced feed lubricating der es for enines' and like apparatus, comprising the combination of a lubricant receptacle, an oil ump, appropriate valves, a ratchet wheel by which the oil pump is operated, a pawl rod engaging the ratchet wheel to ell'cct its ste by step rotation, means for adjusting the length of the pawl rod to regulate the point at which it engages the ratchet wheel, an 'expansible dia hragni mounted upon a stationary part 0 the apparatus ant (-Ol' Suchadjustment may read-' lit) vmriabic fluid pressure.

nected with a chamber adapted. to be subjected to variable fluid pressure.

3. Forced feed lubricating devices for encombination of an ricant receptacle, an oil pump, appropriate valves, a ratchet wheel 0y which the oil pump is operated, .a pawl gines and like )aratus, comprising the rod adjustable in length engaging the toothed wheel to effect its step by step rotation, an expansibie dia pin'egm mounted. upon a sta; ticnar'y part 0' the apparatus andconnected with chamber adapted to be subjected to 4. id creed ieeu lubricating devices for engines and apparatus, comprising an expansihle diaphragm m0unted upon 'a stal tionary part of the apparatus and adapted to be subjected to intermittent fluid pressure whereby its intermittent ex ansion and contraction is caused, oil feed evices connected with the diaphragm and intermittently 0perated thereby and a valve operating to cut off the fluid pressure from the diaphragm when a desired degree of' expansion of the latter has been attained.

In testimony whereof, I have hereunto subscribed my name.
